Linterna-MATRIX.

Specification of Letters Patent.

Patented March 30, 1909.

Application filed November 19, 1908. Serial No. 463,848.

To. all whom 'it may concer/L:

Be it known that l, Hummer-i Decanen, of lilollmaimstrasse 26, Berlin, German Enr pire, manager, have invented certain new and useful Improvements iin Linotypeiviat riees, ot' which the following is a specifica.- tion.-

My invent-,ion has reference to matrices for linotype-machines such as shown in Letters Patent Nos. '4,36 531 436 532- and analogous These natrices, eachy containing 1none edge one or more matrix-cavities, are stored in a magazine, from which they are released successively in the order in which their characters are to appoarin print. and assembled in line` the composed lino being wedge spaces, transferred to a mechanism tor castingthe slug or linotype against it.

The object of the present invention is to prevent the matrices trom being injured by the entrance ot' molten metal between them during the casting operation. To this end it is ynecessary that the side taboe ot the matrices around the type characters 'will lit closely together when they are assembled in line,

My invention consists, essentially, in a matrix having on the one side tace the upper and the lower end reduced in tliiekness, While .the middle portion containing the type clniractersx rests untouched.

ln the accompanyingg` drawing l ha vo shown a matrix in term specially adapted tor use .in the Mergentiialer linotype, but it to be understood that my improvements are applicable to all cil-citatine,` matrices: used in linotype-.maciiines. matrix mzzl-ting.;- machines or analogous typographie ma chinos.

Figures l. and f2 represent side viens eln a vvmatrix in accordance with my inv ition.

Referring to the drawing the represented with ears or lips a at the .tour corners and with the intaglio character or matrix proper i) in one edge and the distributingdeetli e in the upper end. It will be observed that lwhen a series of these matrices are assembled side by side they will present their characters in a common line. In this position il, is necessary that the side faces of the mirt- 'riees will fit closely together, the opposite sides ofthe body portion containing the inatrix cavity are therefore parallel. To 'facilitate the manufacture of these parallel side Yfaces already before this invention the middle portion@ was reduced in thickness is also very d-ilticult to Work these two snr--y faces exactly parallel, and the surtaees are large enough to enable the dust and the small metal portions to rest between, they being; an obstacle to the tittinpy close of the matrices. In order to remedy these disadvantages, it has already been attempted to shorten the ledges in question byA o;- setting them at both sides oiE the nmt'rix and leaving the -full height only to the central portion inclosing the type. These means could not. however be suceesetul, as on the one hand, owing to the ollisetting of the lugs, ditliculties were caused moreover the Wedges of the spaces between the letters used to slide on an excessively Small .surface ol't the .n1at1'iccs, so that the latter were thus quickly Worn out. My improvement consists in reducing the said surtacee on one side only et thc matrix bar, so that the middle portion c hasl the full thickness while the upper and the lower portions f are reduced in thickness.

The essence of the invention lies in reducingA the thickness only on 'the one side and on (lio side opposite to the ears or lips U. ly this; arrangement the ears c rest undamaged and ,l have no litiirulties in the distributing' operation. Besides l treat tcnderly the thin side walls of the matrices in ihe viifstit'yinnr operation. rthe operation is dono by willige-spaces llorinetl ot two relatively sliding' wedges one of which .is provided with rshoulders. by which it is held lirinly in the line while the other mounted iuovahlv. Huch a spacer has the objection that it injures the matrix by the Sliding movement and this would be .still greater it the sii-lodare ot the matrix bordering on the spacer is reduced. ,lherefore l leave un# touched this side ol' the matrix on which the ypace bar slides, and only reduce the sur- Ytacos on 'the other side as shown in the drawing'.

llnving,` thus described the nature of my iu\v'ention, what desire to secure by patent is:

l. A linotype matrix having ears which are smaller in thickness than the matrix body and lie flush with the one side face of the matrix, this side face of the matrix being in distrilniting, and' smooth from top to bottom while on the opposite side the face is reduced on the upper and the lower end, substantially as described.

2. A linotypeinatrix having ears which are smaller in thickness than vthe matrix body and lie flush with the one side face of the matrix, this side face of the matrix being smooth from top to bottom while on the opposite side the face is reduced on the upper and the lower end', and has a middle portion of full thickness containing the type characters, substantially as described.

A linotype-matrix having the middle portion of the side faces reduced in thickness from top'to bottom and havingcontact faces consisting of two parallel surfaces, and.

also having ears which are smaller in thickness than the matrix body and lie flush with the one side contact surfaces of the matrix, the surfaces on this side being smooth from i; top to bottom while on the opposite side the lportion of the side upper end aud have a surfaces are reduced on the lower and t'ne upper end, substantially as. described.

4. A linotyp'e-matrix having themiddle ness from top to bottomand having contact faces consisting of two parallel surfaces, and also having ears which are smaller in thick-v ness than the matrix body and lieflush with the one sidev contact-surfaces of the matrix,

the surfaces on this side being smooth from top to bottom while on the opposite sideitlie surfaces are reduced thickness containing the type characters, substantially as described.
